JOSEPH H. SYMONDS, OF SWAMPSOOTT, MASSACHUSETTS.

Moron-can WHEEL.

No. 913,580. Specification 01 Letters Patent. Patented 10.23, 1909.

Application filed June14, 1907, ,Serial No. 377,254.

To. all whom it'may concern;

Be itknown that I,.Josrrn'H. Sntoxns, a citizenof the United States, residing at- "Swampscott, inthe county of Essex, State *The present mv'entron has reference to bwheels designed for motor vehicles, and it aimsto. provide a strong, durable, and eflicient resilient wheel in which the pneumatic cushion is completely protected against ac-f cidental deflatiorfi from'pnncture or otherwise by the casing of the wheel liub.

I The invention further aims to provide means for preventing any accidental displacement of the cushion with-in the casing; for retaimng the internal bearings of the axle 1n place within the hub casingnfor def' creasing the frictional wear upon said bear ings; ar d for preventing the entry of dust or grit into the casing.

WVith, the above and other ends in view,

the invention consists in the construction combination, and arrangement of parts,.all

as hereinafter fully described, specifically claimed, and illustrated in the accompanying drawings in which like parts are desi nated by corresponding referencenumera s in the several news.

Of the said drawings, Figure l is a front elevation, partly in section, of a wheel constructed'in accordance with the present invention, 2 is an enlarged axial sectidn therethrough, Fig. 3 is an enlarged perspective view of one of the members of the internalbearihg, Fig. .4 is a similar view of the other bearing member, Fig. 5 is a detail view of'theldust cap,.Fig. 6 is an inverted perspective view of the dust'guard, showin the inwardly projecting flange formed thereon, and also the felt washer, Fig. 7 is an axial section through a modified form of easing.

Re erring more particularly to the drawings the numeral 8 indicates the axle of the wheel upon the ends of which the steps 9, l0, and 11 are formed, the steps beingof radually decreasing diameter, as shown. h/Iounted upon said step ed end is the hub casing which, in the pre erred construction, consists of outer and inner plates, 12 and 13,

between which the trough-shaped spoke rim 14 is fittedjtt'he inner ends of the spokes 15 being disposed in said rim-,'-while their reduced upperendsfit in openingsfior'med in the felly "16 t9 which the cushion tire 17 and its clamping plate 18 aresecuredn Each of the casing plates is provided with'an axial plate; being closed by'th dust-guard 20 projectin tubular sleeve or flange 21 which is formed integral therewith and fits upon the innermost step 9 of the axle, The dustguard is further provided with an annular washer 22 of felt or similar material, which is secured to its'innr face and bears directly against the outer face of plate113' adjacent cosed by aic'up-shaped dust-cap 23 hereinafter more fully described. 1 W f Disposed completely withinthehub' casing is an internal bearing for the axle,-whi'ch an outer member 25, each 1nember"having a plane, circumscribing'fiangepr extension 26 which-bears against the inner face ,oft-he adjacent plate, as shown in Fig.- 2 These bearing. members are so disposed as toembrace the central step 10 ofth'e axle and are each provided with an axial opening through which the axle passes, the diameter of said openings being'somewhsit great 1' than that of the axle step 10, to admit of the interposition of the pairs of inner and outer races 27 and 28, between which the angularly-disposed anti-friction rollers 29 are-fitted, the opposite'end of each. series of rollers being engaged'in perforated spacing-rings 30 and 31.? The mutually'adjacent inner ends of the bearing members overlap each other, as shown in Fig. 2, the inner member 24 having such end undercut to form a seat adapted to receive the adjacent end of the outer memslightly offset, or directed inwards towards theaxle, these'off'set portions 32 serving as steps to prevent the pairSpf races from moving towards each other.

I The overlapping ends of the bearing menr ed with a series of registering formed during its molding andfprior to its vulcanization. Owing to this construction, it will be apparent that the the will be pos tively held in place within the casing, and it's.

accidental displacement prevented. .Thetire thus rests upon the bearing members directly above the oifs'et portions 32 thereof," the-outer faces of said members being slightly .con-f' caved, as shown. The tire'isi'n'fla'ted bmeans ofa tube 35 which extends-throug an opening-36 formed in the bearing member 25, access to the tube beinghad througlri ithev opening 19 in the plate'l v p The dust-cap 23 which closes the openin" justreferred to is cup-'s'haped'jas shown, an

its threaded-inner end 'i's engaged with the threaded wall which surrounds said opening and "is somewhat widened, or. flared, the outer-face of the 'ca 'having 'aperi heral shoulder 37 which a uts against sai wailthus limiting the-movement of the. cap. a The 'nuts 38, which are secured onto the threaded outer step 11 of the a-xle,'-ar'e completely" 'incased by the on said'nuts preventing bodily movement 9 the hub in one-direction and also preventing displacement of-"thet;

While the casing ispreferably. formed of" three separate parts, a. e.., the plates 12 and I 13 and the s oke-rim or channe1 1e,- it.'wi11 be obvioust at such construction is not an essential of the invention, as the casing may be formed in two matingpart's l3 and 14 What is clai1 ned,i s, r 1. Thecom'blnation, in a wheel, of a central hub-j casing; a pair of oppositely-diszposedtaxle-bearmgs located within the caswhich are bolted together, as shown in mg and having their mutually-adjacent j ends'overlapped, said overlapping ends having-registering perforations formed therethrough a pneumatic cushion inclosed by casing and surrounding said bearings;

;:and a series of pins carried by said cushion, "and positively engaged in said perforations,

'for preventing displacementof said cushion.
